I am so looking forward for this drama. I wish Lee Kwang-soo had a major role. I watched him in "Sound of Your Heart", and he is so funny!!! However he gets some cameos or incremental roles in movies and dramas. He should be really busy with varieties, but still...

Oh my god, the news that come out from this drama has so far been pitch-perfect at hyping me up.

I'd love to see some of his female film co-stars like Park Bo-young and Kim Yoo-jung on his cameo list.

I live for Cameos!! Give me all the cameos!! The cherry on the cake would definitely be Jun Ji Hyun's appearance...one can always dream right?

daebak cameos from cha tae hyun as usual! he's really my favourite korean celebrity, beating all eye candies. ?

there's a new videoclip for the drama. J2's MV. it's 90's galore. haha

Is Jang Hyuk standing on a box to make him look taller? Ha!

90s idol, you say? Then a Kim Jong Kook cameo is a must! It would be a piece of cake since he's also bestfriends with Cha Tae Hyun and Jang Hyuk!!!

Hmmmm.....this is shaping up to be another Producer, interesting.

JANG HYUK! ❤️❤️
...standing on that box though. LOL

So many great cameos. Gosh, this drama wasn't on my to-watch list, but it sounds pretty interesting.

I knew it, I knew Cha Tae Hyun will bring all of his friends into this drama. I'm glad I wasn't wrong. And Dong gu looks so good with his black hair and even in that retro outfit.

This is great! Cameos are always welcome, and it seems he has a lot of friends to call on to support him. Maybe his film co-stars could drop by as well? ? Lolol at Jang Hyuk being "Bluetooth Man". He looks so cool in the stills though. Maybe he's a secret agent? That would surely throw Yoon Shi-yoon's character in for a loop. . .

Wahahhaa it is Jang Hyuk !! Definitely watching this for him. And btw Voice was not that scary, you should give it a try.

Hoping this is another repeat Producers, but with a much more interesting concept and lively cast/story/characters.

I love Mr. Cha. +++++

Imagine being Cha Tae-Hyun's children and having all these celebrities as your uncles and aunties.

I thought he would appear as himself, the rapper, in the 90s timeline. :D

well no wonder if it is Mr. Cha.
Do you watch 2d1n? Cha Taehyun even invited Jo Insung to become 2d1n's guest. I never saw Jo Insung in varietyshow before, so i was so shock hahahaha

lol Why is Jang Hyuk standing on wood. I always assumed he was tall enough.

Any chance we can get Bogummy to cameo? Cha Tae Hyun made a semi-serious phone call to Park Bo Gum asking him to guest on 1N2D and Park Bo Gum, being the sweetheart that he is, actually took that semi-serious phone call to heart and actually did take time to go out and make a guest appearance on 1N2D just days after the phone call, even when he was super busy and was in the middle of shooting "Moonlight..." at the time <3

Thanks for that great news, Buhdoop!

"Bluetooth Man" sounds like a super hero. I've been wondering when I'm going to be seeing Jang Hyuk again. He's overdue for a swashbuckling sageuk after last year's turns in BEAUTIFUL MIND and VOICE.

Looking forward to Ahn Gil-kang's cameo, too. I think the last show I saw him in was ORANGE MARMALADE. I think PUCK! was the most recent I saw with Lee Kwang-soo. THE BEST HIT is shaping up to be a blast.

Jo Hyun-jae is another 90s idol I'd love to see in a cameo. Could we get a BREAD, LOVE AND DREAMS reunion with Joo Won before he heads off to the service? Pretty please? ;-)

Jang Hyuk oppa! ?????

lol @ the title "high-class" cameo.

Wow!! Can't wait for Jang Hyuk's cameo and for this series to kick off!!

Bluetooth man. I love it.

Hahaha I got a bit confused when @buhdoop referred to Jang Hyuk as "Dae-gilaaaaa". I didn't watch Chuno and usually don't remember characters' names very well, unless you know, the character's name is repeated a lot in the drama (e.g. You From Another Star's "Do Min-joon sshi-iii!!" and Whisper's "...This is Lee Dong-jun", which Lee Sang-yoon kept repeating whenever he was on the phone lol). Bottom line: I read "Dae-gilaaaaa" as "Dae" (대) which I took to mean "big", and "Gila" which in the Malay language means "crazy".... xD So yeah. I was like. Who is this person called "Big Crazy"..?! Oh wait, no, oops. It's "Dae-gil" plus an exclaimation "ah". *sheepish*

This drama had me at YSY but then they had to add KMJ, and the two Cha's and now this... overkill and I'm so happy.

Why do this year's dramas keep topping each other on the anticipation factor. I can't keep up with the hype.

The man even brought Jo in sung to participate in 1N2D . Nuff said.

I miss seeing him in Suits like with IRIS 2 so this is good.

Oh man, I LOVE fish-out-of-water tropes! I'm watching Tunnel right now and I get a kick outta every time Kwang-ho reacts to new technology and things he comes across. Anyways, this looks funny already! I can already imagine Yoon Shi-yoon freaking out. It's also amusing to see Jang Hyuk standing on so many platforms, lol! I like all of the actors that are gonna cameo, so it looks like fun. Can't wait!

Jang Hyuk! ??Can't wait to see episode 2!! He looked so cool in suit! I agree that he is using the wooden box as the hoverboard while filming.Without the box, he seems to be the same height as Shi Yoon.

We need Kim Jong Kook to cameo as well!

Cool, CTH really has lots of good friends!

Watch here Yoon Shiyoon and Hong Kyungmin as the 90s duo J2 :) https://www.youtube.com/watch?v=qt1W52sDeck

Wait... is Kwang-soo's picture the one from the drama? What's with the hairstyle? I can't. Haha.

I'm looking forward to this one so much it's making my head spin.

CTH deserved all the love from fellow actors and actress bcos he's not only a great actor but also a great human being and a great friend indeed.

Hey, maybe they can finagle Oh Man-seok into a cameo while they're at it.

Yoon Shi Yoon's outfit that is one awesome outfit! True representation! Lee Kwang Soo! Jang Hyuk! June 2 come sooner.
